PROTECTIVE COVER FOR DRAWING-BOARDS AND THE LIKE Filed April 25, 1963INVENTOR Gabor Hegeclus ATTOR United States Patent 9 3,229,661PRQTECTIVE COVER FOR DRAWING-BOARDS AND THE LIKE Gabor Hegedns, 164Stinson St, Hamitten, Ontario, Canada Filed Apr. 25, 1963, Ser. No.275,708 1 Claim. (Ci. 24267.1)

The present invention relates to a protective covering for drawingboards and the like and it consists in the combinations, constructionsand arrangements of parts herein described and claimed.

Generally there is provided a flexible cover for a drawing board or thelike and which is normally spring-held within a casing which is mountedat one end portion of the board but which may be withdrawn from thecasing through a slot provided therein to extend over the top of thedrawing board when the latter is not in use, as for example, at night.Manipulating the free end of the cover acts to free the spring device toagain draw the cover within the casing when it is desired to utilize thedrawing board or the like in conventional manner. The device is suchthat it keeps the drawing board or the like free of dust which mightotherwise accumulate over night or at other times when the board is notin use.

It is accordingly an object of the invention to provide a device of thecharacter set forth which is simple in construction, inexpensive tomanufacture and yet effective and eflicient in use.

Another object of the invention is to provide a novel cover for drawingboards.

Still another object of the invention is to provide a device of thecharacter set forth having novel means for storing and permittingwithdrawal of a cover forming a part of the invention.

Other and further objects of the invention will become apparent from areading of the following specification taken in conjunction with thedrawing, in which:

FIGURE 1 is a botom plan view of an embodiment of the invention,

FIGURE 2 is a top plan view thereof, partly broken away, to illustratecertain details of construction,

FIGURE 3 is a fragmentary perspective view of a housing forming a partof the invention,

FIGURE 4 is a fragmentary perspective view, partly broken away, of anend casing forming a part of the invention, and

FIGURE 5 is a side elevational view, partly broken away, illustratingthe device in use upon a drafting board or the like.

Referring more particularly to the drawing, there is shown therein adevice of the character set forth comprising an elongated tubularhousing having a longitudinally extending slot 11 therein, the endportions of the housing adjacent the slot being inturned, as indicatedat 12, to prevent injury to the fingers of the user and to a coverforming a part of the invention when the device is in use.

An end housing 13 is grooved, as indicated at 13a, to receive one end ofthe housing 10 and is integrally provided with a bracket 14 having anopening 15 therein for the reception of screws 17 whereby the same maybe "ice attached to a drawing board 18, as indicated in FIGURE 5 Thecasing 13 is also provided with an inwardly extending lug 19 centrallyapertured for the reception of a pin 20 affixed to one end of a roller21.

The other end of the housing 10 is provided with an end casing 22likewise having integrally formed therewith a bracket 23 apertured, asindicated at 24, for the reception of screws 17 whereby the same may beattached to the board 18.

The roller 21 is spring loaded and provided with the conventional pawland ratchet mechanism indicated at 26 and is also provided with a slotfor receiving the conventional end portion 27 of the spring mechanism.

A flexible cover 25 is afiixed at one of its ends to the roller 21 andextends outwardly through the slot 11 and its free end has mountedtherein, by sewing or the like, a bar 28. A pull ring 29 is centrallyfastened to the bar 28.

In operation, it will be apparent that the device may be aflixed to theunderside of a drafting board 18, as indicated in FIGURE 5 and that,when it is desired to protect the board 18 and any papers which may bepositioned thereon, it is only necessary to grasp the ring 19 andwithdraw the cover 25 from the housing 10 against the act-ion of thespring mechanism as clearly shown in FIGURE 5. When it is desired to nolonger utilize the cover, the ring 29 may be manipulated in customarymanner to free the spring mechanism and allow the cover 25 to againwithdraw through the slot 11 and again wind itself upon the roller asshown, for example, in FIG- URE 4.

While but one form of the invention has been shown and described herein,it will be readily apparent to those skilled in the art that many minormodification-s may be made without departing from the spirit of theinvention or the scope of the appended claim.

What is claimed is:

A protective covering for a drawing board comprising a cylindricalhousing of sheet metal having a longitudinal slot therein, inwardlyturned edges of said sheet metal along each side of said slot, endcasings supporting said housing at either end thereof, grooves formed insaid end casings for mating engagement with said housing, a rollerwithin said housing rotatably mounted in said casings, a spring rewindmechanism associated with said roller and one of said casings, bracketmeans integral with said casings for attachment to the underside of oneend portion of a said board with said longitudinal slot oriented anddirected downwardly, a flexible cover attached at its inner edge to saidroller and extending through said slot, a bar mounted in the free edgeportion of said cover, and a pull ring centrally affixed to said bar.
